it is a requirment for a client for testing reasons. I don't see anything wrong with the setup to be honest.

it is required for testing only. for a live system it would not be worth while but seeing as they client doesn't have a spare ISDN30 circuit both Callmanagers MGCP gateways will be directly connected via E1 crossover. They have spare E1/T1 cards in the gateways that I had setup for PLAR's out to TDM Dealerboards so it's not like they are wasting money. They are using the equipment they have there already plus both Callmanagers are located in the same room.

Like I said, for testing purpose only

Many thanks for the people who had posted to this thread and a big thank you to Gordon for clearning this one up for me
